RE: Class D , Class-a , Zmin and phase is Very important

Nelson Pass talks allot about the portion of the transistor S curve you want to be working in and for lower signal levels he selects very particular transistors, some of which are custom made for him in small batches, e.g. JFETs.

Look at his white papers. I just don't remember which ones discussed this directly. It is part of what drove the philosophy of the First Watt designs.

You get that jump factor when you operate at the low end of the S curve as you come close to the asymptote at the center of the S. Pass is not in favor of operating there but does. The class B operation of his amps generally starts above that if I understood it correctly.
